In computing, a module is a unit of software that is designed to be independent, interchangeable, and contains everything necessary to provide the desired functionality. [1] The term "module" may sometimes have a more specific meaning depending on the context. This page describes a few types of modules with their corresponding documentation pages.
Disambiguation
Lmod modules
Also called "environment modules", Lmod modules are used to alter your (shell) environment so as to enable you to use a particular software package, or to use a non-default version of certain common software packages such as compilers. See Using modules.
Python modules
In Python, a module is a file of code (usually Python code) which can be loaded with the import ... or from ... import ... statements to provide functionality. A Python package is a collection of Python modules; the terms "package" and "module" are frequently interchanged in casual use.
[2]
Certain frequently-used Python modules such as Numpy can be imported if you first load the scipy-stack Lmod module at the shell level.
See SciPy stack for details.
We maintain a large collection of Python "wheels". These are modules which are pre-compiled to be compatible with the Standard software environments. Before importing modules from the our wheels, you should create a virtual environment.
Python modules which are in neither the scipy-stack Lmod module or in our wheels collection can be installed from the internet
as described at Python#Installing_packages|the Installing packages section.
The main Available software page is a good starting point. Other related pages:

StdEnv/2020is the default collection of Lmod modules - Lmod modules specific to Niagara
